Whilst wandering around Ebay I found THIS (http://cgi.ebay.co.uk/LANCASTER-DALLMEYER-AUTO-FOCUSING-ENLARGER-WITH-LENS_W0QQitemZ7601339570QQcategoryZ29987QQrdZ1QQcm dZViewItem) and I am wondering how on earth it works :confused: . Does it work using reflectance or what?

Very puzzled :confused: :confused: :confused:

The auto-focus Leitz enlargers I've used in the past use a cam to keep the image in focus as the head moves up and down. Perhaps this does too. It sure doesn't use anything high-tech!

Well that is interesting ... um I'd be a little scared to have something that looks liek THAT in my darkroom ...

Certainly not too high tech.

The way most auto-focus enlargers work is that you set the focus after loading a negative, then they stay in focus as you change the magnification. That makes it *much* easier to print a full frame, since you don't have to go through the maddening cycles of adjusting head height, adjusting focus, and finding you've overshot *again* -- it usually takes me 5-6 cycles to get close enough to a full frame print, if that's what I'm after.

Looks like you could fill it full of soapy water and check inner tubes for leaks.

What size of film d'ya think it takes - cos it looks like it could take a truly enormous neg. :) :)
Just right for the Cirkut? :D

Must be old. I haven't seen electrical flex like this for years. Reminds me of the way little girls' had plaits in the 1950's before I realised there was a difference.

Maybe that's what happened to AA's horizontal enlarger.

Hi Lachlan

A quick Google tells me that Lancaster cameras were quarter plate (3.25 x 4.25 inches) so presumably the enlarger is as well. No mention of actual size, but the 15 postage seems reasonable if you wanted it!

Lachlan: Just buy it, figure it out and let us know. And tell us how much water of the gods was required to make it work.

Don't bet on it being quarter plate, I've got a half-plate Lancaster Instantograph and I'm pretty sure they went past full plate.

I would guess that it a dual bulb diffusion light source - a bulb on each side with maybe an opal glass diffusion plate in front of each, maybe a mirror, to try an eliminate the hotspot a single bulb gives on a large neg... Somebody email the guy for a picture of the inside...

Dunno mate, still, I might buy it to be buried in when the time comes.

It says that the lens is 4". So the negative size must be 1/8 plate or smaller. Probably enlarges to a fixed size paper. It's "autofocus" because it's fixed focus. The early Leica enlargers were just long boxes with a negative holder on one end, a paper holder on the other, and a fixed lens between - the light source was whatever you wanted to use (the sun?).
